In the 1990s. two sisters had a very strange time slip type experience in a Leeds newsagents. Here is their original post of the account in a US website (now defunct):

One Thing Leeds to AnotherSisters Find Themselves Out of Phase in a U.K. Newspaper ShopIt was 1998 on a summer's morning in Leeds. My sister and I were on our way to work and decided to popinto the paper shop. (Whether this is relevant I don't know, but the shop is situated in a building built around1899). My sister was in front of me as we approached the shop door, and through the glass panel I saw awoman browsing at the magazine section, immediately to the left of the door entrance.It looked as though this woman would be in our way as we entered the shop but as we did my sister didn'tseem to be aware of her. I [told my sister], "Mind that woman," but she carried on walking and went rightthrough her and the woman faded away. [Only then did] my sister stop and ask, "What woman?"I walked ahead of my sister a little further into the shop and turned to her and told her, "I think I've just seen aspirit -- you just walked through this woman." My sister was adamant she saw no one. We both looked aroundthe shop. The lights were off, which I thought was odd; it seemed very gray and eerie. It was the kind ofatmosphere you'd expect in the early hours of a winter morning -- but this was summertime during businesshours. Though all the shelves were stocked like they should have been, we were the only people there. Mysister mentioned it was cold, and she said she felt something funny was going on. I felt this too. I said, "Weneed to get out of here."We left the shop but lingered outside the door. I described the woman, who had been in modern-day dress, tomy sister, and she asserted, "There was no one there -- the shop was empty." (Upon later comparison, I foundthat my sister saw everything I saw apart from the woman.) We were outside the shop door for all of a minutewhen I asked my sister to come back in with me. When we entered the shop, the lights were on and it was fullof customers -- school kids, people on their way to work, etc. Had I looked more carefully at the people in thestore the second time we entered, I feel I would have seen [the woman my sister walked through].The usual woman was behind the till, but she was staring at us with her mouth open. My sister said, "Whatthe hell is going on? Where did all these people come from?" I was just in total shock. I walked to the till withmy sister and bought some cigarettes; as the woman served us, she looked quite terrified. I'll never forget thelook on her face. We left the shop and to this day still can't get our heads round it. We did go back around amonth later to ask the woman if she noticed anything odd, but there was a man serving. My sister said she'dbeen back a few times and has never seen her again. We did ask the man if anyone had ever mentionedanything about the shop, but I think he thought we were loons.--MandyOne Thing Leeds To Another https://web.archive.org/web/20070303101 ... aol.com/...1 of 1 25/02/2015 18:06

I recently managed to make a brief contact with "Mandy." Her sister had died but she was happy to discuss their experience, and told me the location of the incident: Taheri's newsagents at 85 Rounday Road. HS Hardware has since taken over the shop.

Mandy has now abruptly stopped answering my emails, and I have attempted unsuccessfully to make contact with Mr Taheri via the new shop owner. It is clear from the account that the shop assistant must have observed the sisters entering the shop, the first one passing through the customer by the door, then both fading away. This must be the only reason why she would have reacted with extreme fear when the girls went back in. Mandy thought she might have been Mrs Taheri. From an evidential point of view, locating her and getting her account of the event would provide a nearly unique opportunity (I know of only one other time slip case with a similar potential).

If anyone knows anything about this case, or would be interested in maybe helping to locate the 3rd witness, I would be extremely grateful!
